2 million point Data Logger with USB output to Flash memory
Doppler Flow Meter
Measure flow from outside a
pipe. The Greyline DFM 5.1 is designed for "difficult
liquids" that would damage regular flow meters -
wastewater, slurries, sludge, chemicals, viscous liquids and
abrasives. There is no obstruction to flow and no pressure
drop. The non-intrusive, clamp-on ultrasonic sensor fits any pipe 1/2" (12.5
mm) Inside Diameter or larger. The
electronics/display enclosure can be mounted nearby.
Use the isolated 4-20mA to
transmit flow to remote displays, recorders or controllers.
The programmable relays can be used for flow control, pump
protection or flow proportionate pulse. Calibration is easy
with the built-in 5-key calibrator. Display and totalize flow
in your choice of engineering units (gallons, liters etc.)
Sensor cable can be extended up to
500 ft. (152 m) with no loss of signal. The standard sensor is rated
non-incendive for Class I, Division 2 hazardous locations and the DFM 5.1
can be equipped with optional Intrinsic Safety Barriers for sensor
installation in Class I, Division I hazardous locations. Other options
include extra control relays and a built-in 2 million point Data Logger
with USB output to Flash Drives.
The DFM 5.1 includes a new digital
signal processor to filter background noise and interference, and to
measure flow rates accurately in liquids containing gas bubbles or solids
The DFM 5.1 Doppler
Flow Meter includes Greyline's user-friendly calibration system.
Use the built-in keypad to select pipe diameter and units of
measurement. It's easy. You can calibrate the flowmeter in just a
Consider the new handheld
PDFM 5.1 Portable Doppler Flow Meter . It also works from outside the
pipe with a clamp-on ultrasonic sensor, and includes a large digital
display, totalizer and 4-20mA output.
